We dissolved 3-5 tbsp of borax in each container (depending on size) with slightly warm water.
Then we created our snowflakes out of white pipe cleaners which you can hang on the glasses with more pipe cleaner or with chopsticks/pens/whatever long skinny objects you may have.
Let them sit overnight and the next day you'll have borax snowflakes!
We hung them up to dry all December and they were very pretty. I expected the borax crystals to easily fall off when I was moving the snowflakes but they did not. We will definitely make these again!
